Sedum plant named ‘Thundercloud’

ABSTRACT

A new, distinct  Sedum  plant as shown and described, characterized by pointed foliage, white flowers and a larger height compared to the seed parent.

Latin name: Sedum hybrid.

Cultivar name: ‘Thundercloud’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct hybrid of Sedum plant named ‘Thundercloud’ characterized by pointed or fingered foliage, white flowers and a larger height compared to the seed parent. The new Sedum was raised as a seedling from open pollinated seed sown as an unknown Sedum tatranowii, not patented, in Hebron, Ill. in 2005. The selection of the new plant was due to its' larger pointed foliage, larger white flowers and a taller height compared to the seed parent. Initial asexual reproduction has taken place at a nursery in Hebron, Ill. since 2006 by means of division, and vegetative cuttings. The new Sedum has shown to be stable and identical in reproduction to the parent after rooting over 1900 plants from 2006 to 2009.

SUMMARY OF THE INVENTION

The new Sedum plant named ‘Thundercloud’ characterized by pointed foliage, white flowers and a larger height compared to the seed parent have been observed to be unique and stable.

Plants of the new Sedum can be compared to plants of Sedum spectabile ‘Stardust’ not patented.

-   -   1. The new Sedum plant is a hybrid and does not produce seed         while Sedum spectabile ‘Stardust’ is fertile and produces seed.     -   2. The new Sedum plant has a mature size measuring 25-30 cm high         and 40-45 cm wide while Sedum spectabile ‘Stardust’ measures         45-55 cm high and 55-65 cm wide.     -   3. The new Sedum has white flowers with a hint of pink in them         while Sedum spectabile ‘Stardust’ is entirely white.

Plants of the new Sedum can also be compared to the seed parent plant Sedum tatranowii, not patented.

-   -   1. The new plant is a hybrid and does not produce seed while the         seed parent plant is fertile and produces viable seed.     -   2. The new Sedum has a mature size of 25-30 cm high and 40-45cm         wide while the seed parent has a mature size of 12 cm high and         30 cm wide.     -   3. The new Sedum has larger foliage measuring on average up to 2         cm across by 5-6 cm long while the seed parent has foliage         measuring 6 mm across by 2 cm long.     -   4. The new Sedum has a stem thickness of 5-8 mm while the seed         parent has stem thickness of 2 mm.
